BT5-4640 24V Super Heavy-Duty A/C Compressor – SD7H15-SHD, Ear Mount, 1-Groove 132 mm, GK Head

Description

Overview

The BT5-4640 SD7H15-SHD compressor is engineered for 24V mobile air-conditioning systems commonly used in agricultural, construction, and off-road equipment. Because of its ear 8-long mounting design, the compressor provides enhanced stability in high-vibration operating conditions. At the same time, the single 1/2-inch belt drive and 132 mm clutch support consistent power transfer.

Additionally, this unit uses a GK-style rear horizontal pad head with O-ring sealing, which allows for clean hose routing in both OEM and aftermarket installations. As a result, the BT5-4640 integrates easily into replacement and retrofit systems across multiple heavy-duty platforms.
